Background

Interleukin-1β (IL-1β) is a proinflammatory cytokine produced predominantly by activated monocytes and epithelial cells (1). Precursor IL-1β is cleaved by caspase-1 and mature IL-1β is then secreted (1-3). Target cells include macrophages and many other cell types. Signaling by IL-1β involves IL-1β binding to IL-1 accessory protein (IL-1-AcP); the complex then binds to IL-1RI (1,2). Signaling occurs through activation of MAP kinase and NF-κB pathways (1,2). IL-1β also binds to IL-1RII, which lacks an intracellular signaling domain and thereby serves as a high affinity decoy receptor. IL-1β binding to IL-1RI is inhibited by the negative regulator, IL-1R antagonist (IL-1Ra). IL-1Ra binding to IL-1RI does not signal and serves to block IL-1β signaling. IL-1β plays critical roles in the acute phase response and sepsis (1-3).

IL-1β是主要由激活的单核细胞和上皮细胞产生的促炎因子(1)。IL-1β的前体被caspase-1剪切,成熟的IL-1β紧接着被分泌(1-3),目标细胞包括巨噬细胞和许多其它的细胞类型。IL-1β的信号传递过程包括IL-1β结合到IL-1附属蛋白上 (IL-1-AcP); 这种复合体紧接着结合到IL-1RI (1,2)。这种信号传递会激活MAP激酶和 NF-κB信号通路(1,2)。IL-1β也结合到IL-1RII,它缺乏细胞内的信号区域并因此作为高亲和性的诱捕受体。IL-1β结合到IL-1RI的过程能够被负调控因子IL-1R拮抗剂IL-1Ra所抑制。IL-1Ra结合到IL-1RI后无信号转导并且作为抑制剂阻止IL-1β信号通路。IL-1β在急性响应期和脓毒病中发挥了重要的作用(1-3)。
